Amy Rose is a hedgehog from Sonic's planet. She has a REALLY HUGE crush on Sonic, but is also his very close friend. She can be loud, bossy, annoying and rude at times but she will still do anything for her friends, sometimes even enemies.
Amy appears to be sweet and innocent. In reality, she is mean and really dangerous. Amy can be extremely stubborn, never taking the hint that Sonic doesn't like her in the way she likes him. Amy is known to be agressively short tempered, punching things out of rage with her Piko Piko hammer. Sometimes even when someone simply mentions Sonic. Knuckles will often try to stop Amy from her violent ways but she refuses.
